Our Authentication Process
Our team of experts created the first and most trusted glass grading system. With over 45+ combined years of collecting glass, we’ve consulted with thousands of the members of the glass community for a unique and trusted grading scale intended for reliability, consistency, and transparency.
Our grading scale is out of 5 points with the classifications below:
D5: DeadStock Mint
VD5: Virtual DeadStock Mint
4.5-4.74: Very Good
3-3.49: Near Poor
2-2.49: Near Very Poor
1-1.99: Very Poor
Conditions and intensifiers that determine
the score of your glass.
A DeadStock Mint (D5) is glass that is authentic, has never seen water or been used, and is authenticated in hand.
A Virtual DeadStock Mint (VD5) is glass that is authentic, has never seen water or been used, and is pre-authenticated by the artist or verified sellers to be new and authentic. Pre-authenticated glass from verified sellers on the marketplace will be fully authenticated by our team before receiving your item.
A mint (5) represents glass that is virtually perfect. There are no chip/crack, scratches/flee bites, label fades, or staining on the glass.
Anything between a 4.75-4.99 (excellent) is a near-perfect piece. It may contain a minuscule amount of damage to the glass. This can include minuscule scratches/flee bite, chip/crack, label fades, and staining.
A very good condition (4.5-4.74) represents an item that may have more than one minuscule damage to the glass or one slight condition to the glass, including a chip/crack, water stain, label condition, or bloom.
Good condition (4-4.49) represents glass with one major flaw or a couple of intermediate flaws and minuscule/slight flaws.
Fair condition (3.5-3.99) is glass that may have one major flaw and most likely an intermediate/slight flaws.
Near Poor condition (3-3.49) glass may have multiple major flaws and potentially other flaws that may range from minuscule to intermediate. Pieces in this category are borderline in poor condition.
Poor condition (2.5-2.99) glass has multiple major flaws allowing the piece to visually appear it has endured damage over its lifetime.
Near Very Poor condition (2-2.49) glass will have at least 3 to 4 major flaws. A piece in this condition may start losing a visual appeal to the eye.
Very poor condition (1-1.99) is glass that has at least 4 major flaws and another minuscule or intermediate flaw on the glass. The glass has gone through advanced stages of wear and tear it barely has an appeal to the eye.
An unacceptable condition (0-0.99) is in the worst condition possible failing to meet an acceptable standard. It will have at least 5 major flaws with at least another minuscule to an intermediate flaw. The glass has advanced defects that the glass has lost the eye appeal entirely.
We use qualifiers to signify a condition or characteristic of glass that meets all the criteria for a particular grade but fails the standard in one area.
